High heel shoe

ABSTRACT

There are disclosed high heel shoes where separate components combine to create load balancing internal footwear technology. A two-piece system includes interlocking toe bed and shank constructed of complex three dimensional curved surfaces which create an intricately sculpted volume to provide structural support down the length of the entire foot. The toe bed provides a wide base and keeps the big toe pointed straight (at an approximately 10° angle). A heel maximizes the surface area of the bottom of the heel at the point of strike with the ground while retaining a minimal and aesthetically appealing silhouette from the side view. The toe bed and shank feature a composition of layered materials which when combined work to provide both stability and shock absorption to the ball of the foot during the foot strike of walking. An internal support structure provides a padded barrier and intermediary between the rigidity of the shank and the softness of the shoe upper.

Description of the Related Art

High heel shoes are very popular for their aesthetic appeal. However,high heel shoes are typically not very comfortable and can cause pain ina wearer's foot when worn for prolonged periods of time. The use of highheel shoes and the elevation of the wearer's heel shifts the balance ofthe coronal plane of a body from back to front. Due to the shift of thecoronal plane from back to front, the center of gravity of the bodyshifts towards the ball of the foot. This change of balance demandscompensation in posture by other parts of the body causing the knees tobend slightly forward and pushing the hips and spinal cord out ofalignment. This results in an increased amount of pressure on the ballof the foot rather than the heel bone. The change of the center ofcoronal balance pushes the weight of the body uncomfortably onto themetatarsals, sesamoids or floating bones of the foot instead of anatural distribution of force onto the heel bone.

Various methods for enhancing the comfort level of high heeled shoeshave been attempted, such as inserts. However, inserts do not fit allshoe types and attempt to compensate for a poorly shaped shoe ratherthan correct the shoe itself.

Shoes typically are referenced with front, rear, top and bottom, whichare all taken from the frame of reference of the wearer. Typical highheel shoes have three primary components, uppers, heel and sole. Theuppers are at the top of the shoe and help hold the shoe onto the foot.The sole is between the foot and the ground. The heel provides lift andsupports the heel of the foot.

The sole of a high heel shoe typically has an outsole, an insole whichmay include cushioning and a shank which is between the outsole andinsole and which bridges the outsole to the heel. The outsole is theexposed part of the sole that is contact with the ground. The outsoleprovides grip with the ground and durability. The sole often includes aninsole which is disposed above the outsole and provides a platform uponwhich the foot can operate. Where the ball of the foot sits on the soleis called the toe box. The shank supports the foot and the weight of thewearer. The shank is what provides the structural support, and strengthbetween the heel and the ground, allowing the shoe to create the ‘lift’of a high heel. The shank is akin to a support beam in architecture. Itsupports the foot and weight of the wearer at the angled position of theshoe.

The heel raises the rear of the shoe in relation to the front. The heelincludes a seat where the heel of the wearer's foot sits in the shoe.The distance the wearer's heel is raised is called the heel height, andheel height is defined as the distance from the top of the toe box(where the ball of the foot rests) to the top of the seat. Heel heighttypically is between 20 mm to 140 mm, though higher heel heights can beaccomplished with an accompanying platform under the toe bed section ofthe shoe. A top piece of the heel is where the heel comes in contactwith the ground. The heel breast describes front face of the heel. Athin high heel is called a stiletto. The pitch is the angle between thetoe bed (where the forefoot rests) and the heel seat (where the heelrests). In traditional heels, the incline, between the toe bed and theheel seat is a flat, angled plane, due to the flatness of the steelshank inside the sole. The lift is the total increase in a wearer'sheight while wearing the shoe. The bottom of the heel which comes incontact with the ground is referred to as the heel tip or top piece.

Shoes are open, closed or partially open, based upon whether the top ofthe foot is covered by the upper. If open or partially open, the upperincludes straps, such as at the front (toe), mid, ankle or rear (heel).

DETAILED DESCRIPTION

The functional components of the shoes described herein have a varietyof specifications. These specifications include dimensions, shapes,thicknesses, strength, rigidity and flexibility, including variations ofthese throughout the component. The specifications of many of thecomponents are related such that changes to one component suggest orrequire a change to other components. These specifications are selectedbased upon the intended wearer or range of wearers, such as ranges ofweight and shoe size. Furthermore, intended use of the shoe, includinguseful life, may guide performance and tolerance requirements, whichthen impact specifications of the components. In the followingdescription, a number of relative terms are used with respect to variousshoe components. In practice, these relative terms serve as guides tohow to achieve specific dimensions for a desired shoe.

Referring now to FIG. 1, the main structural components of a high heelshoe 100 include a toe bed 110, a shank 120 and a heel 130. The shank120, the toe bed 110 and the heel 130 are strong and rigid enough tomaintain structural integrity and support the wearer during the intendeduse of the shoe 100. Through a composite, interlocking structure ofthese three structural components of the high heel shoe 100, forcesimparted by the wearer are more evenly absorbed and distributed toprovide a more comfortable experience.

The components 110, 120, 130 have geometric details to create aninterlocking mechanism for assembly. The toe bed 110 attaches to thefront of the shank 120 and the heel 130 attaches to the rear. Thecomponents 110, 120, 130 include joints (not shown) which ‘click andlock’ into place, such as with a one quarter turn. The interlockingmechanism creates structural continuity between the toe bed 110, shank120 heel and 130, working to distribute loading between the componentsand avoiding the weak joints where standard shoes traditionally break,such where the heel joins the body of the shoe.

The toe bed 110 includes a composition of layered materials which whencombined work to provide both stability and shock absorption to the ballof the foot during the foot strike of walking.

Unlike a conventional shank which is merely flat, stamped spring steel,the shank 120 extends from the wearer's toe area to heel area, andacross the foot from left to right, is not flat but has varyingthicknesses and varying outer dimensions. Unlike a conventional shank,which is a flat piece of spring steel and begins at the heel and endswhere the shoe connects to the ground, the shank 120 has a precisionsculpted geometry of varying thickness and varying dimensions. Think ofit like a ski slope—on the traditional shoe, the wearer's weight comesdown the flat incline of the steel shank and crashes down onto the floorhard. With the custom curved geometry of the shanks disclosed hereinwhich match the underside geometry of the human foot, the slope issofter, and the ‘skier’ or ‘load’ does not crash hard into the groundbut rather goes down in a more controlled way. These improved shanksprovide arch support via the asymmetry in the part's left and right side(in one shank, not referred to the left and right side shoes). Eachshank has increased height toward the inside of the foot, to again matchthe geometry of the underside of the foot. Since the wearer's archescreate a higher ‘ceiling’ on the inside of the foot, these improvedshanks are designed with a higher curve on the inside. Thus, the contactbetween the foot and the sole unit is maximized. This provides archsupport which shifts weight off of the toe bed and back towards theheel, and improving load distribution. Furthermore, there is an increasethe overall amount of surface area connecting the foot and sole,providing for superior load distribution. Traditional heels put amajority of the load on the toe bed area, but the improved shank changesthis.

The shank 120 may have an outer profile which matches that of the toebed 110, including a taper down as the combination extends from heel 130to the ground below the toe bed 110 for the aesthetic effect of slimmingthe outline of the shoe 100. This aesthetic aspect may be provided inwhole or in part by a welt (not shown).

The form of the toe bed 110 provides a slightly wider base than isprovided by corresponding structures in conventional high heel shoes andkeeps the big toe pointed straight (at an approximately 10 degreeangle). This works to mitigate rotation in the ball of the wearer's footand allows for natural positioning. The toe bed 110 may have a bottomsurface 125 having a coating of a base layer of urethane tread (Shore90) to provide traction with the ground to reduce slipping. The toe bedgeometry is minimizes the displacement of the big toe. Traditional highheel shoes tend to push the big toe aggressively toward the other toes,which causes discomfort, foot damage and difficulty walking for someusers.

Referring now to FIG. 2, there is shown a cutaway side view of the shoe100. An insole cushion 250 is disposed at the top surface of the shank120. The insole cushion 250 forms an internal support structure of theshoe 100 functioning as a flexible, padded barrier and intermediarybetween the rigidity of the shank 120 and the softness of the uppers(not shown). The insole cushion 250 represents an intricate approach tonuanced geometries, and may be made of foam materials which have a broadrange of compression states which can gently conform and support agreater variation of foot shapes. The insole cushion 250 may be made ofa combination of viscoelastic polyurethane foam, commonly referred to asmemory foam, and sorbothane, a viscoelastic polymer, in Shore durometersranging from 30 to 50. The viscosity of memory foam allows the materialto resist shear stress and strain when under pressure, while theelasticity provides a spring back property to provide support, holdingthe foot in compression. Together these properties provide comfortthrough gentle support optimized for a wider variety of foot shapes.

At the toe bed 110, the insole cushion 250 rises from the underside ofthe foot to the back of the foot to spherically support the roundedstructure of the ball of the foot, reducing movement of the foot insidethe shoe 100 during walking. It also runs under the pads of the foot andcontinues around the outer sides of the toe bed 110.

At the wearer's arch, the insole cushion 250 provides a gentle riseunder the midsection of the foot. The goal is to not provide specializedrigid arch support like that of an orthotic shoe insert (which would beuncomfortable if not customized), but to provide a gentle softcompression support across the midsection of the shoe, holding the footin place during walking.

The insole cushion 250 may be created through a combination of sheetfoam (for flat 2D areas) and cast foam (for 3D structures) of bothSorbothane® and memory foam. Sheet foam, in the form of sheet stock, maybe cut to size using a CNC knife. 3D components of the insole cushion250 may be fabricated through reaction injection molding (RIM). The 3Dcomponents are modeled and the 3D model is inverted to create a 3D modelof the mold. To mold memory foam, the two chemicals used to make thefoam (isocyanate and polyol) are heated, mixed together and shot intothe mold. Once in the mold the reaction of the hot mixture causes it toexpand until it reaches the wall of the mold. When the hot mixturetouches the relatively cold wall of the mold a foam skin forms.Depending on the geometries, the 2D and 3D components of the insolecushion 250 may be laminated together and applied to the shank 220 usinga foam fast spray adhesive (such as Claire Mist, Camie 373 or 3M 77)where necessary.

A downwardly-projecting heel pin 231 rigidly fastened to the shank 120extends down into a similarly-sized cavity formed in the heel 130. Theheel pin 231 fits closely into the cavity and is secured therein, suchas with adhesive, a friction-fit, and/or threads. The heel pin 231 maybe metal or other strong, rigid material.

A rib 222 commences generally at the rear edge of the toe bed 110 andextends rearward to the heel 130. The rib 222 is an elongated centralsection of the shank 120 which projects below its bottom surface but notnecessarily to the sides. The rib 222 provides longitudinal rigidity tothe shoe 100 and essentially replaces the strength function of metalshanks that have previously been used in the production of high heelshoes.

Assembly of the shoe 100 may start with forming the shank 120 through atwo part overmolding process. The toe bed 110 and the shank 120 may bemade from a layered blend of polyether copolymer based thermoplasticpolyurethane (TPU), sorbothane (Shore 50), and silicone gel (Shore 20),forming a multi-material composite that works to absorb some of theshock moving from the feet to hips, thus reducing the impact from heelto toe strike during walking. Other internal geometries of the layerswithin the shank 120 and the toe bed 110 may be included, such ashoneycomb structures which enhance shock absorption while increasingsupport and stability.

For aesthetic benefit, the toe bed 110 and shank 120 may be enclosed andhidden in uppers (not shown). The uppers may include fabric, leather orbioleather, enclosures plus adornments (e.g., buckles, laces anddecorative metal and fabric elements). The uppers may entirely encasethe height of the toe bed 110, shank 120 and heel 130, creating acontinuous surface from top of the foot to the ground. The uppers may bemade in conventional processes from leather or other common fabricmaterials and function to encase the insole cushion 250 by wrapping andsecuring the foam elements in place through sewing and adhesivetechniques.

Referring now to FIG. 3, there is shown a second high heel shoe 300.Like the shoe 100, the high heel shoe 300 includes a toe bed 310, ashank 320 (mostly hidden), a heel 330 and an insole cushion 350. Whereasthe toe bed 110 and the shank 120 of the shoe 100 twist, click and lock,in the shoe 300 the toe bed 310 and the shank 320 snap and locktogether. While left and right side views may look the same, the leftand right parts are different. In typical high heel shoes, the shank andheel are the same for the left and the right side. In the shoe 300, theleft and right toe beds, shanks and heels are specific to each side.That is, the structural components of the left shoe and the right shoeare each tuned to provide lateral stability and comfort for the wearer.

The toe bed 310 provides a wide base and keeps the big toe pointedstraight (at an approximately 10° angle).

The shank 320 is shaped to distribute weight for increased comfort. Theshape of the shank 320 provides load balancing under often punishingconditions during use of the shoe 300. The shank 320 is made of amaterial such as nylon that when cured is relatively rigid and hassufficient strength to support the user's weight on the high heel shoe300. The shape of the shank 320 is contoured to the geometry of thefoot. The contoured shape along with the increased surface area comparedto a conventional shank allow the forces of walking or standing to bemore easily distributed through the shoe avoiding pressure points at theball of the foot which cause pain and injury. Pitch is also improved.

There is generally a relationship between lift, stability and comfort ofa shoe. The toe bed 310 and the shank 320 together provide at least 2inches of lift, with 2-4 inches providing a good compromise between adesire for increased height and a desire for comfort and stability. Thisis based upon body geometry of a range of people and a standardconfiguration of the shoe 300 of component size, shape and behavior toaccommodate that range. For a given person's body, there is generally arange where increasing lift has only a small impact on comfort andstability. Eventually, increased lift has increasing impact on comfortand stability. Furthermore, comfort and stability may varyindependently, and an improvement in one may result in a decline in theother.

The heel 330 tapers downward from a relatively large upper end to anarrow lower end having a greater lateral dimension than a longitudinaldimension. This provides enhanced stability to the shoe 300 whilemaintaining a relatively thin and elegant profile from the side. Theheel 330 therefore presents a generally conventional appearance withseveral functional variances which enhance comfort and/or stability. Inthis regard, the heel may taper from top to bottom 335 with maximizedsurface area of the bottom 335 at the point of strike with the groundwhile retaining a minimal and aesthetically appealing silhouette fromthe side view. This is achieved through the base shape of an oval orlozenged rectangle whose long dimension is at the heel breast 336 andprovides up to triple the amount of striking surface of traditionalstilettos. This increased surface area helps mitigate strain from footstrike and provides further balance support in the lateral direction,critical for walking in any areas of irregular or rough terrain. Theheel 330 is further contoured in gentle curves in both the side and backviews, furthering the appearance of an elegant minimal aesthetic similarto that of a traditional stiletto. The heel 330 may be made of athermoplastic polyamide blend substrate, such as glass filled nylon,mixed to create maximum structural support while retaining impactabsorption crucial for heel strike.

Referring now to FIG. 4 there is shown an exploded perspective view ofthe structural components of the high heel shoe 300 from above.

The insole cushion 350 is shown separated from the shank 320 but theymay be unitary and co-molded. The insole cushion 350 may cover theentire upper surface of the shank 320, with a plurality of through holes452 in the rear (heel) portion that correspond with through holes 422 inthe shank 320. All but central through holes 422 a, 552 a align withthreaded bores 432 opening upward in the heel 330.

To strengthen the junction of the shank 320 and heel 330, there may be ashaft 431 made of strong, rigid material which extends down into acentral through bore 432 a in the heel 330. The shaft 431 includes anupper reinforced end 431 a. The shaft 431 may be tubular for lowerweight, and may have a cross section of constant or varying shape andwidth, and may taper from the end 431 a toward its bottom, like a dentalimplant. The bore 432 a has a shape and dimensions complementary tothose of the shaft 431 to achieve a snug fit. A friction fit and/oradhesive provided within the through bore 432 a in the heel 430 maysecure the shaft 431 therein. The shaft 431 may extend down to thebottom end of the through bore 432 a, or a lower cap (not shown) may beinserted therein to cover any recesses.

The shank 320 has a central body that extends to both toe and heel endsand to the lateral sides of the shoe, and an upper raised area 425thereform which is relatively shallow compared to an outer edge 427 ofthe shank 320, which is itself thin to minimize weight but thick enoughto provide sufficient support. The upper raised area 425 extends fromthe toe bed rearward to the heel area and fits into a similarly-shapedcavity 352 on the underside of the insole cushion 350 (see FIG. 5). Theupper raised area 425 and the outer edge 427 generally conform to thecontours of the wearer's foot, except for a plurality of forward lobes423 in the upper raised area 425. The lobes 423 may be somewhat bulbousshaped. In the second high heel shoe 300 there are four lobes 423 andthey are splayed outward in a pattern that resembles a gecko's foot. Thegecko's foot shape mitigates the structural loading within the shank 320by distributing forces within the shank 320 and passing them through tothe outsole of the shoe 300. At least two lobes are necessary, and morethan eight lobes generally less beneficial. A central channel 424extends from a forward end of the upper raised area 425 and provideslateral flexibility to the shank 320. In FIG. 8, the central channel 424is more visible. FIG. 8 also shows a curvature of the central spine ofthe shank 320 as designated by broken line 820.

The toe bed 410 has three parts, a middle rigid portion 415 sandwichedbetween a soft lower layer 418 and a number of soft cushions 413. Thesethree layers 413, 415, 418 are of different materials which combine toprovide both stability and shock absorption to the ball of the footduring the foot strike of walking. The lower layer 418 and soft cushions413 may be formed through co-molding with the rigid portion 415 to forma unit. The rigid portion 415 includes a cavity 412 surrounded by anumber of through holes 416 and cells 414 provided between cell walls417. The soft cushions 413 fill the cells 414. Some of the cells 414,such as the two middle cells, may be left without cushions to providesome flexibility in the toe area and enhance comfort thereto. The rigidportion 415 may be made of nylon or other such rigid polymer, while thelower layer 418 and cushions 413 may be formed of a soft polymer such asTPU. An outsole (not shown) is secured to the underside of the lowerlayer 418 and to a portion of the underside of the shank 320.

Though the toe bed 310, the shank 320 and the heel 330 are formedrespectively as units or parts which snap securely together, theirjoints may be enhanced. The shank 420 has through holes 426 in the toeregion which line up with those 416 in the rigid portion 415. Thethrough holes 416 in the rigid portion 415 may be threaded to receivefasteners 455 which pass through the through holes 426 to secure the toebed 310 and the shank 320 together. Fasteners 453 may be installedthrough the holes 452, 422, 432 respectively in the insole cushion 350,the shank 320 and the heel 330. Fasteners 455 may be installed throughthe holes 456, 426, 416 respectively in the insole cushion 350, theshank 320 and the toe bed 310. These fasteners 452, 455 secure therespective parts.

Referring now to FIG. 5 there is shown an exploded perspective view ofthe structural components of the high heel shoe 300 from below.

The upper reinforced end 431 a of the shaft 431 fits closely into arecess 521 a in the underside of the shank 320 concentric with thecentral through hole 422 a (FIG. 4). The recess 521 a and the end 431 ahave complementary shapes and dimensions to permit a close fit.Adhesives may be used to reinforce the connection.

The upper raised area 425 fits closely much like a puzzle piece into thesimilarly-shaped cavity 352 on the underside of the insole cushion 350.

A lower raised area 522 from the central body of the shank 320 has aplurality of forward lobes 523 which together mimic a gecko's foot. Thelower raised area 522 extends rearward from the rear edge of the toeportion of the shank 320 and gradually diminishes prior to reaching theheel region of the shank 320, providing rigidity to the shank 320 muchlike the rib 222 in the shank 120 of FIG. 1 and FIG. 2. The lower raisedarea 522 is relatively thicker than the upper raised area 422 (FIG. 4)and fits snugly much like a puzzle piece into the similarly-shapedcavity 412 (FIG. 4) in the toe bed 310. The lobes 523 provide increasedsurface area for great contact between the shank 320 and the toe bed310.

Referring now to FIG. 6 there is shown a perspective view of the highheel shoe 300 fully assembled. In this view, components of an upper canbe seen, including an insole 660, a counter 680 attached to one or moreheel straps 682, and an arch strap 690.

The insole 660 is secured on top of the insole cushion 350 and coversthe holes 452, 456 and top ends of the fasteners 453, 455 (FIG. 4). Theheel straps 682 may be affixed below the insole 660, such as to theshank 320 or sandwiched between the shank 320 and toe bed 310. The archstrap 690 spans across the shoe 300 and may be affixed like the heelstraps 682.

The counter 680, heel straps 682, arch strap 690 and other parts of theupper may include material (not shown) akin to that of the insolecushion 350. For example, the counter 680 may include two narrowchannels of foam running longitudinally along the sides of the heel 330,holding the tendon of the back of the ankle in gentle compression. Thisprovides structural support to hold the foot in place during walkingwithout attempting to grip at the top of the heel 330, an area whichgenerally gathers blisters from repeated rubbing.

The combination of toe bed 310, the shank 320 and the heel 330 provide aplatform suitable to a limitless variety of aesthetic upper designs. Oneor more straps running across the top of the foot provide support duringwalking, especially during the lifting of the foot. The straps may bealigned with cushions to provide padding and compression which serves tohold the foot in place inside the shoe and increases stability duringstepping. The straps may be disposed midway between the toe bed 310 andthe ankle.

Referring now to FIG. 7 there is shown a perspective view of a shank 720and a heel 730 as alternatives to those 320, 330 of the second high heelshoe 300. To strengthen the junction of the shank 720 and heel 730, anon-circular reinforcing member 724 formed in the shank 720 extends downinto a cavity 734 in the heel 730. The reinforcing member 724 fitssnugly into the cavity 734 and provides a non-rotatable coupling. Themember 724 and cavity 734 may both be hexagonal, or may have differentbut compatible shapes and dimensions. As in FIG. 4, one of the fasteners453 extends downward through a bore 725 in the reinforcing member 724and secures into the cavity 734. Adhesive may also be provided betweenthe reinforcing member 724 and the cavity 724 for added strength, andalso between an upper surface 738 of the heel 730 and a contacting lowersurface 728 of the shank 720.
